A policy think tank has unveiled a new “Common Sense Calculator”, a handheld device it claims will make public debate “more accessible” by converting evidence into a simpler unit: whatever someone already felt.
The calculator resembles a standard pocket model, except it includes several additional buttons labelled “Just Asking”, “Surely”, and “In My Experience”. When a user inputs a number from a report, the screen briefly displays it before the device sighs politely and rounds it down to something “that sounds more like real life.”
Developers said the tool was built for television studios, where data is often introduced only to be immediately replaced by a confident anecdote. “Not everyone has time to process a chart,” a spokesperson explained. “With our calculator, you don’t have to. You press one button and the chart becomes a story about a bloke you once met at a petrol station.”
In a demonstration, researchers entered a figure describing a long-term trend. The calculator responded by issuing a warning: “Too Many Years.” It then offered three alternative outputs: “It’s getting worse”, “It’s always been like this”, and “Nobody’s allowed to say this anymore.” When asked which was correct, the device printed a small receipt reading: “Correctness is elitist.”
The most popular feature so far is the “Intuition” key. When pressed, it replaces any result with a tidy whole number that “feels right”, regardless of the inputs. The device also includes a “Moving Goalposts” slider for users who wish to keep the conclusion while changing the question mid-sentence.
To address concerns about accuracy, the think tank stressed that the calculator is not intended to be right, but to be useful. “It helps people arrive at the destination they were already walking towards,” the spokesperson said. “It’s like a satnav for certainty.”
Early adopters report that the calculator has improved their confidence dramatically. “I used to worry about being challenged,” said one commentator. “Now I just press ‘Surely’ and the numbers apologise to me.”
